PURPOSE:To obtain the coating having wear resistance and corrosion resistance on the sliding face of a sliding parts and yet uniform and beautiful by melting the coating material having wear resistance and corrosion resistance by a laser, etc., and coating by drawing a specific pattern. CONSTITUTION:A coating material 1 is fitted attachably and detachably to a spindle 2, which is linked to a vibration piece 3 and the electromagnet 5 vibrating the vibration piece 3 is fitted to the bed 4 fitting one end part of the vibration piece 3 by a screw, etc., to excite an exciting coil 6. The coating material 1 and a sliding part 15 are covered by a cover 23 to feed the reaction gas of an inert gas, etc., by a hose 25 from a bomb 24 therein. An NC device 26 controls the exciting power source 27 driving servomotors 14, 17, 19 by their controlling and exciting the exciting coil 6, controlling as well the work power source 27 impressing a discharging voltage between the coating material 1 and sliding part 15. A dot-like, belt-like or circular body is coated by optionally being selected on the sliding face of the sliding part 15 by this NC device 26. |
